Instrument Setup

There are three components involved in the PDDI setup, the host computer (PC), the phase-resolver unit (PRU) and the PDDI itself. Each of the following three sections describes the connections to one of the parts, then the operation of the complete system is outlined.

Connections to PDDI

The PDDI requires the following connections:

1. Three fibre-optic connections. To each of the three numbered fibre-optic connectors attach the corresponding fibre-optic cable end. These connectors provide serial data in, serial data out, and trigger gate in. The trigger gate in cable is controlled by the phase-resolver unit, to enable triggering for specific phase intervals.

2. Signal input. To the input BNC connector supply an input signal whose maximum amplitude must not exceed the values shown in the following table, as a function of the current amplifier and attenuator settings:

-6dB attenuator	-20dB attenuator	+20dB amplifier	+20dB amplifier	Net gain factor	Maximum signal
Off	Off	Off	Off	1	300 mV
Off	Off	Off	On	10	30 mV
Off	Off	On	Off	10	30 mV
Off	Off	On	On	100	3 mV
Off	On	Off	Off	0.1	3 V
Off	On	Off	On	1	300 mV
Off	On	On	Off	1	300 mV
Off	On	On	On	10	30 mV
On	Off	Off	Off	0.5	600 mV
On	Off	Off	On	5	60 mV
On	Off	On	Off	5	60 mV
On	Off	On	On	50	6 mV
On	On	Off	Off	0.05	6 V
On	On	Off	On	0.5	600 mV
On	On	On	Off	0.5	600 mV
On	On	On	On	5	60 mV
3. AC power. Connect the PDDI unit to AC power, ensuring that the internal jumpering is set correctly for the local line voltage. Jumper settings are diagrammed near the power supply inside the case.

4. Optional amplifier stage output monitoring. To the monitor BNC connector attach a cable, that may be used to view the output of the amplifier/attenuator/filter stages.

Connections to PRU

The purpose of the PRU is to do fibre-optic to RS-232 conversion, and programmable phase gating of the PDDI’s trigger signal. The PRU requires the following connections.

1. Three fibre-optic connections. To each of the numbered fibre-optic connectors, connect the corresponding numbered fibre-optic cable end.

2. RS-232 DB-9 connector. Connect a 9-pin serial cable to this connector. The other end will be attached to the host PC.

3. AC Power. Connect the wire from the 12VAC wall transformer to the corresponding socket on the PRU.

4. Phase reference input. If the AC power to the PRU is to be used as the phase reference, set the switch on the PRU to the position nearer the AC input connector. Otherwise, set the switch to the other position, and supply an phase reference to the BNC connector on the PRU. Use a maximum signal amplitude between 1V and 10V for this signal.

Connections to the PC

The PC requires connection of the 9-pin serial cable from the PRU to the COM1 serial port.

Basic Operation

Once the PDDI and PRU are powered, start the PDDI host software (pddi.exe) on the host PC. The following sequence of steps will allow the user to do basic data collection:

1. Do the Connect to PDDI command on the Control menu.

2. Enable both attenuators in the Standard Settings dialogue on the Control menu before connecting the input signal, to reduce the chance of damage to the instrument (see maximum input ratings above).

3. Choose the Raw Waveform display on the View menu.

4. Set the Trigger Value on the Control menu to about 10% of the full scale value in the Raw Waveform plot.

5. Choose the Start command from the Control menu.

6. If no signal is observed after the conclusion of the data transfer from the PDDI, then successively switch off attenuation or switch in amplification and retry the Start command (one increment at a time) until a signal is observed.

7. The filters may be switched in to reject unwanted signals in various frequency bands, if these, rather than the desired PD pulses, are causing triggering of the PDDI.


Troubleshooting

This section describes user-level troubleshooting only. That is, activities that can be carried out without disassembly of the PDDI, and without signal measurements on the circuitry within the PDDI or PRU. What follows is a draft troubleshooting procedure, to be augmented as field experience with the PDDI is accumulated.

General checklist for straightforward ‘no-go’ problems

-- Are all connections made as described in instrument setup?

-- Are PDDI and PRU receiving power? Check connections to AC power, and look for faint red glow from two of three numbered fibre-optic sockets on PRU and one of three on PDDI. Inside the PDDI case, LEDS should be glowing on the large main board and its two mezzanine assemblies.

-- Was the PDDI powered up before starting the PC host software? If not, restart both.

A terminal emulator program (e.g. Hyperterm, bundled with Window O.S.’s), set to use COM1 at 38.4Kbaud, 8 bits, no parity, 1 stop bit, should see a signon message on powerup of the PDDI.

General checklist for post-connection problems

If the host software receives no diagnostic messages when the Connect to PDDI command is issued (i.e. the command completes successfully)...

-- Are relay clicks audible from the PDDI as individual filters are selected/removed in the Standard Settings dialogue? (Clicks happen when OK button is clicked)

-- Does the Raw Waveform display show any signal, with trigger level set to the first value larger than zero, after the capture, download sequence initiated by a Start command?

-- Is the signal peak amplitude at the monitor output BNC connector between 10mV and 300 mV?

-- Setting the Draw Waveform Bars check box in the Plot Options dialogue, are all of the coloured bars in the Raw Waveform Plot following the trend of the input signal? Each colour represents a different data channel. Unresponsive bars are usually indicative of a calibration problem with the digitiser mezzanine assemblies on the PDDI main board. We are still collecting data on the stability of the digitiser calibration.

Data interpretation issues

-- Do all peaks captured have similar phase? In the presence of repetitive signals above the trigger threshold, it is possible for PDDI memory to capture its maximum capacity of 32 events within a tiny fraction of a single 50/60Hz cycle. Possible solutions are to filter out unwanted signals with the notch filters, or use the (slower) phase-scan acquisition mode to guarantee a complete survey of possible phase ranges, in the presence of frequent triggerings.

-- Do the peak histograms appear unchanging from one Start command to the next? Make sure to use the Clear Accumulators command between distinct experiments. The default behaviour of the software is to accumulate peak data across multiple start commands.

-- In the 3D plots, count axis scale and time axis scale are settable in the Plot Options dialogue. In a long experiment, in which (for example) a cable voltage is increased slowly over time, it is possible to use the Repeater Settings dialogue to configure the software to keep collecting data for the duration of the experiment, without repeatedly issuing a Start command. Changing the voltage about once per minute would guarantee sampling at each voltage level without further interface actions.


Phase Resolver Unit

Phase Resolver Unit (PRU)

The Phase Resolver Unit is the small box that makes a serial connection to the host computer, three fibre-optic connections to the PDDI, and a power connection. It has two functions, the first is to convert the RS-232 signals into fibre optic signals for long-haul transmission to the PDDI. The second is to perform gating of the trigger-enable signal to the PDDI in order to allow triggering only in particular phase windows. The phase reference may be either the power line feeding the PRU, or an external source, feeding the BNC connector (max. 10Vpk-pk). The choice of phase reference is switch-selectable. Connect the PRU to COM1 of the host computer. Connect the numbered fibre-optic ports of the PRU to the corresponding numbers on the supplied fibre-optic cables. Connect the other ends of the fibre optic cable to the corresponding numbers on the PDDI. The PRU and PDDI should be powered up before the PDDI host software is run.

Connect to PDDI command

Connect to PDDI command (Control menu)

Use this command to open a connection to a PDDI instrument, that is attached to the host serial port via the phase-resolver unit (PRU). Both the PRU and the instrument should be turned on before the software is started.


Acquisition mode, standard
 Acquisition Mode, Standard (Control menu)

This configures the software to do data collection by enabling triggering for one or more intervals as specified in the Repeater Settings dialogue. When the Start command is issued, the trigger window is opened for the specified Trigger Wait Duration, then the collected data is transferred, a total of Number of Tirgger Waits times. When running in Standard Mode, the trigger window opening is not synchronized with phase, but the phase of each trigger event is recorded.


Acquisition Mode, Phase Scan

Acquisition Mode, Phase Scan (Control menu)

Use this command to enable “phase bucketed” data collection. In this mode, when the Startcommand is given, successive triggering windows are synchronized with successive phase intervals, so that a survey of pulse activity in different phase regions is produced. Parameters controlling this scan are set in the Scan Mode Settings dialogue. The “Number of Phase Slices” controls the number of divisions to make in the 360 degrees of phase (e.g. 4 slices => each is 90 degrees of phase). The “Trigger Wait Duration” specifies the amount of real time to spend collecting data for each phase slice. At the conclusion of the Trigger Wait Duration, collection stops and any captured peaks are downloaded for display, then the next slice is initiated.


Transfer Mode, Binary

Transfer Mode, Binary (Control menu)

Use this command to set the data transfer mode between the host and the PDDI to binary, which is the default and usual mode. This provides for faster data transfer than the alternative, ascii mode, which is used solely for debug purposes.


Transfer Mode, ASCII

Transfer Mode, ASCII (Control menu)

Use this command to set the data transfer mode between the host and the PDDI to ASCII. This mode is slower than the usual binary mode, and is used for debugging only.


Standard Settings

The Standard Settings Dialogue allows switching of the various attenuators, amps and filters available in the PDDI instrument, as well as control of the PDDI clock rate.

The PDDI runs normally with the individual digitizer clocks each running at 250 MHz. The only reason to use slower clock rates would be to capture very wide peaks that did not fit in the capture interval available with the 250 MHz clock (a little under 1 microsecond wide). With the 125 MHz clock, an interval of about 2 microseconds may be captured. With the 32 MHz clock, an interval of about 8 microseconds may be captured.

The filters, amps and attenuators may each be switched to be inline (or not) between the input and the digitizers.

CAUTION: The PDDI contains no input protection for the digitizers. At no time should the instrument be run with signals larger than 1.5 times the full scale of the raw waveform display. Exercise care when switching on either amplifier, because each increases the signal amplitude by at the digitizers by a factor of ten. (Notice that “full scale” with both amplifiers switched in is about 3 millivolts!)


Scan Mode Settings

The Scan Mode Settings Dialogue allows setting of the parameters controlling scan mode data collection. This is the mode in which triggering is enabled for successive intervals of phase, to provide for collection of peaks from a complete range of phase values even when pulse counts are very high (i.e. when available memory (32 events) fills quickly once the trigger is enabled). The settable parameters are:

Trigger Wait Duration	The real time interval over which to collect data for the given phase slice
Number of Phase Slices	The number of slices into which to divide the phase axis. (e.g. 8 provides 45 degree slices)


Start

Start (Control menu)

Use this command to initiate data collection. In Standard Acquisition Mode, the software will enable triggering for a total of ‘Number of Trigger Waits’ intervals of length ‘Trigger Wait Duration,’ as specified in the Repeater Settings Dialogue. Peak data collected will be added to the accumulator, which contains all peaks collected since the last ‘Clear Accumulators’ command. In Phase Scan Acquisition Mode, the Start command will enable triggering for a total of ‘Number of Phase Slices’ intervals of length ‘Trigger Wait Duration,’ as specified in the Scan Mode Settings Dialogue. In this case, triggering is enabled for only those parts of the interval that also fall within the desired phase slice.

In both modes, collected data is transferred from the PDDI to the host after each Trigger Wait Duration collection interval.


Repeater Settings Dialogue

This dialogue allows setting of the parameters that control Standard Acquisition Mode:

Trigger Wait Duration	The length of time for which triggering is enabled
Number of Trigger Waits	The number of (acquire, data transfer) cycles to run

Set the Trigger Wait Duration for a short time, unless trigger events are very rare. Setting the Number of Trigger Waits to something other than 1 allows hands-free data collection in an experiment where an experimental parameter is being varied, say, once every minute, and long-term changes are to be recorded.


Clear Accumulators

Clear Accumulators (Control menu)

Use this command to reset the number of stored peaks to zero, and reset 3D plots with a time axis to begin plotting at t = 0 minutes.


Trigger Value Dialogue

The Trigger Value Dialogue allows setting of the trigger threshold level. The behaviour of the trigger threshold is somewhat idiosyncratic, because at the hardware level, the threshold is set in digitiser sample units, yet it is reported in input millivolts, tenths of a volt, or tenths of a millivolt, depending on which amplifiers and/or attenuators are switched in. When the dialogue is launched, digitiser trigger level is read from the PDDI, translated into the corresponding input voltage level, and reported in the value box. The user may reset the value in the dialogue to any value within the dynamic range of the instrument, given the current amplifier and attenuator settings. This set value is translated back into hardware units, accounting for the effect of the amps and attenuators, and sent to the instrument. The user may notice, on next launch of the trigger value dialogue, that the value reported is different than that set. This is due either to discretization error in the available hardware trigger levels, or due to a change in the amps and attenuators selected.
